[Lazarus] Getting a Field list of a record

[Alejandro Gonzalo]

You could use a variants instead of records, an enumeration list could keep track of the "field names".
Your user clause has to include variants.  Here is part of a procedure I used for another purpose:
 
var aRecord : variant;
      i : integer;
begin            
for i := 0 to Dataset.FieldCount-1 do
    aRecord[i]:= Dataset.Fields[i].Value;
